Detection device with nose landing gear protection function through detection of nose landing gear of aircraft

The invention provides a detection device with a nose landing gear protection function through detection of a nose landing gear of an aircraft. The detection device is technically characterized in that an upper flat surface of a rotating support is connected with a detection trolley upper support cylinder, a lower flat surface of the rotating support is connected with a transition support cylinder, the upper flat surface and the lower flat surface of the rotating support apply torque on a torque sensor when the upper flat surface and the lower flat surface of the rotating support turn to different directions, and the value of the torque can be displayed on a display device. The detection device with the nose landing gear protection function through the detection of the nose landing gear of the aircraft has the advantages that the turning angles and the bearing torque of the nose landing gear of the aircraft can be measured in real time when a rodless aircraft tractor tows or pushes the aircraft, and the variable values of the parameters can be displayed on the display device. The values can be used for being compared with over-limit turning angle values and over-limit torque values which are given by an aircraft manufacture under the conditions of models, weights and speeds of different aircrafts, and therefore the turning angles and the torque which the nose landing gear of the aircraft is subjected to when the rodless aircraft tractor tows, pushes, turns, speeds up and brakes can be detected and are enabled not to exceed the over-limit turning angle values and the over-limit torque values.
